个体识别对于跨物种的社会行为至关重要。识别是否由专门用于社会信息处理的电路介导一直是一个争论的问题。在这里，我们研究的神经生物学基础的个人视觉面部识别在Polistes fuscatus纸黄蜂。与其他刺激相比，同种黄蜂的正面图像广泛地增加了许多大脑区域的活动。值得注意的是，我们确定了一个本地化的神经元在proocerebrum，这表明专门的选择性面向黄蜂的图像，我们术语黄蜂细胞。这些黄蜂细胞编码有关面部模式的信息，与面部身份相关的整体活动。黄蜂细胞与灵长类动物的面部细胞惊人地相似，这表明专门的电路可能是神经结构的适应性特征，以支持视觉识别。
Individual recognition is critical for social behavior across species. Whether recognition is mediated by circuits specialized for social information processing has been a matter of debate. Here we examine the neurobiological underpinning of individual visual facial recognition in Polistes fuscatus paper wasps. Front-facing images of conspecific wasps broadly increase activity across many brain regions relative to other stimuli. Notably, we identify a localized subpopulation of neurons in the protocerebrum which show specialized selectivity for front-facing wasp images, which we term wasp cells. These wasp cells encode information regarding the facial patterns, with ensemble activity correlating with facial identity. Wasp cells are strikingly analogous to face cells in primates, indicating that specialized circuits are likely an adaptive feature of neural architecture to support visual recognition.
